Compliant-Coating-Fluid Interaction: Coating Longitudinal Waves in Stationary Fluid

摘要

The presence of a thin non-homogeneous layer at the interface of an elastic and a fluid medium can alter the energy exchange between the two media. In this report the effect of the transition layer upon the propagation of one-dimensional longitudinal waves is analyzed. The motion of the lower boundary of the elastic layer is assumed known and the energy radiation into the fluid is obtained.
